Walmart Company mainly produces and sells bearings.
Bearing brands: KYY, SKF, FAG, NSK, NTN, KOYO, TIMKEN, etc.
Products are widely used in mechanical equipment, machine tools, textile, electrical machinery, precision instruments, road engineering machinery, railway and other fields.
Walmart company with the customer front, the prestige front, the quality front, for you to provide high quality bearings.
The function of the bearing: it is to support the rotating shaft and the parts on the shaft, maintain the rotation accuracy of the shaft and reduce the friction and wear between the shaft and the support.
Bearings can be divided into sliding bearings and rolling bearings according to the nature of friction at work.
Ball bearings mainly consist of four basic elements: ball, inner ring, outer ring and cage or retainer. The general industrial ball bearings meet the AISI52100 standard. The balls and rings are usually made of high chromium steel, and the Rockwell C-scale hardness is between 61-65.
Ball bearings are generally used in low-load mechanical transmission equipment.
Spherical roller bearings have double-row rollers, the outer ring has a common spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This ingenious structure makes it have self-aligning performance, so it is not susceptible to the influence of the angle between the shaft and the bearing housing on the error or shaft bending, and it is suitable for installation errors or shaft deflection caused by angle errors. In addition to being able to withstand radial loads, the bearing can also withstand bidirectional axial loads.
Automobile bearings include: wheel hub bearings, clutch release bearings, gearbox bearings, pulleys, tensioners, idlers, differential bearings, cross shafts
High-quality bearings can avoid frequent car breakdowns and make your safety more secure.
Electrically insulated bearings are bearings with alumina coating.
Are designed to prevent electric current from passing through the bearing.
Have the external surfaces of either their inner or outer ring coated with an insulat-ing aluminium oxide layer, by applying a sophisticated plasma-spray process for an outstanding quality inish.
Are a very cost-effective solution com-pared with other insulation methods.
Slewing bearings are widely used in modern industry. They are called "joints of machines". They are mechanical places that require relative rotational movement between two objects, but also need to bear axial force, radial force, and tilting moment at the same time. An important transmission component necessary. With the rapid development of the machinery industry, slewing bearings have been widely used in marine equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery, amusement equipment industry, photovoltaic solar energy and other industries.
